I tried a bit with HTML::Parser an I hate it because I think it's complicated to use. But parsing HTML with RegEx quickly become more complicated than parsing with HTML::Parser.
So here's my snippet and I hope it'll help you:
# This script will extract text which is incuded in <b>
use strict;
use HTML::Parser;
local $/;
my $html = <DATA>;
my $p = HTML::Parser->new(api_version => 3,
start_h => [\&b_start_handler,"tagname,self"]
);
$p->parse($html);
sub b_start_handler {
my ($tagname,$self) = @_;
return unless $tagname eq 'b';
$self->handler(text => [], '@{dtext}' );
$self->handler(end => \&b_end_handler,"tagname,self");
}
sub b_end_handler {
my($tag,$self) = @_;
my $text = join("", @{$self->handler("text")});
print "$text\n---\n";
$self->handler("text", undef);
$self->handler("start", \&b_start_handler);
$self->handler("end", undef);
}
__DATA__
<P class=para><a name="watch dog"></a><b>watch dog
-</b> A big dog that makes sure that you don't do anything that you're
not supposed to).</p>
<p class=para><a name="WR"></a><b>wooden round –</b> A big piece of ro
und wood.</p>

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
